perf vendor events s390: Remove UTF-8 characters from JSON file

Commit 7f76b311 ("perf list: Add IBM z16 event description for
s390") contains the verbal description for z16 extended counter set.

However some entries of the public description contain UTF-8 characters
which breaks the build on some distros.

Fix this and remove the UTF-8 characters.
